深圳东门61号大院基坑支护设计与施工
摘要:深圳东门61号大院项目临近地铁和浅基础房屋，基坑开挖深度17.15 m和18.60 m。基坑支护设计根据不同周边环境和地质情况采取咬合桩、冲孔桩、旋喷桩、内支撑及锚索等多种支护形式，运用三维数值分析方法对基坑施工进行模拟计算，分析了基坑开挖过程变形情况及其对地铁的影响，确保了基坑的安全施工，为同类基坑开挖提供了一个很好的工程实例。
Abstract:The project of shenzhen east gate No.61 compound is located in east gate commercial street,Luohu,Shenzhen,it is adjacent to the subway and existing shallow foundation buildings.The depth of excavation is 17.15 m and 18.60 m.According to surrounding environmental requirements and geologic conditions,various types of bracing system such as secant pile,punching pile,rotary jet grouting pile,internal supporting system and anchor cable were selected.The construction of deep excavation were seriously simulated by the three-dimensional numerical simulation method.Based on the results of numerical analyses,foundation pit deformation and its impact on subway were studied.Design and construction has been completed and proved to be effective,which provide valuable references for similar projects in the future.
